Meguro Parasitological Museum

Yeah, ew. Probably the grossest museum in Japan, this spot was established in 1953 by Satoru Kamegai, a local doctor concerned by the increasing number of parasites he was encountering in his practice due to unsanitary postwar conditions. The grisly centrepiece is an 8.8m-long tapeworm found ensconced in the body of a 40-year-old Yokohama man. Although there’s not a lot of English signage, little explanation is necessary (or even welcomed) as you can easily see how some of these nasties might set up house inside you. Fun for the whole family! Entrance is on the ground floor of a small apartment building.
